ト速度計。 It is equipped with a unit switch consisting of two sheets of conductive metal foil stacked with a piece of paper in between, and a measurement circuit consisting of a resistor and a capacitor connected in parallel with this unit switch, and a plurality of the above unit switches are arranged one on top of the other. A high-speed metal jet is fired from one direction of the unit switch stack, and as the metal jet advances, the paper is destroyed, and the two conductive metal foils are successively short-circuited and the switch is closed. In a metal jet speedometer that reads from the output voltage of the measuring circuit, a switch made of two sheets of conductive metal foil stacked on top of each other with the paper sandwiched in between is placed in a coated bag made of a material that does not inhibit the progress of the metal jet. An underwater metal jet speedometer characterized by being encased and pressurized with gas inside, and the lead wire extraction part sealed and sealed waterproof.
